Diagram for question 51
AI Explanation
The correct answer is D. The shape indicated by the letter D in illustration D045NG represents a daymark used to indicate the starboard side of the channel when approaching from seaward. This is because daymarks in the shape of a triangle pointing upwards are used to mark the starboard side of a channel, as per the U.S. Aids to Navigation System. The other answer choices (A, B, and C) represent different shapes that are used for different purposes, such as marking the port side of a channel or serving as regulatory markers, and are therefore incorrect for indicating the starboard side of a channel.
